MotorVac offers the ICS Kit, to use as part of the Carbon Clean System. Use it in conjunction with the Carbon Clean Service or on it’s own as part of a regular maintenance program. The ICS cleaning procedure cleans the intake plenum and the intake manifold runners by utilizing the convenient spray bottle along with MV4 detergent. The MV4 detergent’s foaming action clings to the walls of the plenum and intake manifold runners to safely dissolve the gum and varnish buildup.
